In the past course has been recorded with a pen-plotter and highly expensive custom graph paper. The KW991 uses a low cost dot matrix printer and plain paper (roll or fan-fold), and it prints intelligently in plain text, along with time.


The data may be recorded on a PC using a free data logging program, as a simple Voyage Data Recorder.


GPS input provides timing. A routine log of position and speed over ground is printed. The output data rate is variable, automatically, to this simple rule, to minimize the use of paper.


Product Description

•Printout on low cost printer
•Digital heading repeater
•Low cost replacement for “course recorders.”
•Connects to a gyro and a GPS.
•Highly reliable, 1000s in service.


The KW950-E is programmed to output a single line of data at certain intervals. The data is printed on a tandard low cost printer, or to a PC for recording on disk. The interval between outputs varies according to these rules, in order to
minimise paper used, and to provide a good record of data.


a) One line output every 6 minutes on a 6 minute interval. (0, 6, 12 etc. 1/10th hour.) Paper usage on passage would be typically 4 pages per day.
b) An output if course changes by 2 degrees from the last output. This occurs no faster than at a 10-second interval. Paper usage during manoeuvring would be typically 3 pages per hour.
c) An output on demand by pressing the keypad AL button.




DC and rectified unsmoothed DC stepper, 4 to 90v.
360:1 synchro up to 115v/90v. 50/60 400/500 Hz. 90X 400 Hz contactless transmitter.
Tracking rate = Frequency/3 deg/sec. (DC step 333 deg/sec)
Or: NMEA 0183 input, so both input channels are NMEA. Input 1 $HE, AG or GP, HDT,x.x,T


NMEA 0183, GPS data or GPS and heading data.
These sentences provide the data required. $GPRMC or $GPGGA + $GPVTG + $GPZDA.

The system will not function as a course and data recorder without GPS input.
OUTPUT: 4800 baud. 8 bits. No parity. 1 stop bit. 5v CMOS RS422 and RS232 compatible.

Example: time, position, course, speed and course over ground, date.
12:30:00 51 30.521N 003 23.456 W 359 deg 12.0 sog 012 cog 25:12:99

RUDDER ANGLE: If rudder angle (RSA sentence) is input along with GPS data the rudder angle is printed.
